Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural technology, in particular to a greenhouse access management method and system based on an intelligent corridor system. BACKGROUND

[0002] Under the background of modern agricultural intelligence development, as an important carrier of efficient agricultural production, the cleanliness and biological safety control level of the internal environment of the greenhouse directly affect the yield and quality of crops. With the development of greenhouse clustering and patching, multiple greenhouses form a complex interconnected area through corridors or shared passages, and personnel, equipment and materials frequently interact between different functional areas, bringing potential risks of cross-contamination. Therefore, in the access management of such multi-phase greenhouse areas, a technical solution is needed that can real-time perceive the activity state of the target object, predict its behavior intention, and dynamically implement environmental safety control accordingly, to achieve the balance between precise disinfection and efficient passage, and to protect the ecological isolation and safe production of each independent greenhouse unit.

[0003] Currently, some intelligent greenhouse systems use an access management scheme based on the combination of radio frequency identification tags and a fixed reader network. By deploying radio frequency identification tags on personnel or mobile equipment, and placing reading and writing devices at key nodes of the connecting passages of each greenhouse, the system can track the cross-regional behavior of the target object. According to the capture time sequence and position sequence of the tag signal, the system infers the moving path of the target object, and triggers corresponding disinfection reminders or access control instructions in combination with preset access permission rules. However, the existing scheme is limited by the density of the reader layout and the signal coverage range, and it is difficult to continuously and accurately obtain the complete moving track of the target object in the interconnected area, resulting in a lag and uncertainty in judging its direction of travel and destination. Especially in the complex corridor environment where multiple greenhouses intersect, the system often misjudges the target intention due to signal jumping or missed reading, and then triggers incorrect disinfection procedures or access control decisions; relying solely on static permission rules for judgment cannot dynamically optimize the control strategy according to the daily activity patterns of the target object, resulting in disinfection measures that are fixed and redundant, making it difficult to adapt to the flexible and variable access needs in actual production, affecting work efficiency and possibly causing resource waste. SUMMARY

The multi-connected area of the greenhouse refers to the interconnected area formed by connecting multiple independent greenhouses through corridors and shared channels, reflecting the layout form of greenhouse cluster development, and is the associated area of the target object's leaving behavior, and is also the main range of the intelligent corridor system deployment. Historical access mode data refers to a data set formed based on the behavior records of the target object entering the area to be crossed in the greenhouse or leaving the multi-connected area of the greenhouse in the past period of time, including the target object's daily access frequency, weekly access frequency, and corresponding item type records carried during access, reflecting the target object's access rules and carried item characteristics, and used as basic data for determining the initial disinfection process scheme. The greenhouse access management system refers to the core control system with data receiving, data processing, scheme development, and instruction sending functions, used to receive historical access mode data and mobile trajectory data, process data to determine the mobile dominant direction, target greenhouse area, and initial disinfection process scheme, and also can send access permission or prohibition instructions according to the disinfection results, which is the control core of the entire management method. The target object's daily access frequency refers to the total number of times the target object enters the area to be crossed in the greenhouse or leaves the multi-connected area of the greenhouse in a day, which is obtained based on the access behavior records in a day, reflecting the target object's single-day access frequency, and used for determining the disinfection intensity level in the initial disinfection process scheme. The target object's weekly access frequency refers to the total number of times the target object enters the area to be crossed in the greenhouse or leaves the multi-connected area of the greenhouse in a week, which is obtained based on the access behavior records in a week, reflecting the target object's single-week access frequency, and used for determining the disinfection intensity level in the initial disinfection process scheme. Item type record refers to the information recording the specific type of items carried by the target object each time entering the area to be crossed in the greenhouse or leaving the multi-connected area of the greenhouse, which is obtained based on the results of the equipment identifying the target object's carried items, reflecting the characteristics of the target object's carried items, and used for matching the disinfection method in the initial disinfection process scheme.

[0061] In the embodiments of the present application, the intelligent access control device or the sensing device deployed at the entrance of the to-be-crossed greenhouse area and the exit of the multi-connected greenhouse area is used to collect relevant data of the target object entering the to-be-crossed greenhouse area or leaving the multi-connected greenhouse area, and historical access mode data is formed from these data; wherein, the daily access frequency of the target object is obtained by counting the total number of times that the target object enters the to-be-crossed greenhouse area or leaves the multi-connected greenhouse area in a day, the weekly access frequency of the target object is obtained by counting the total number of times that the target object enters the to-be-crossed greenhouse area or leaves the multi-connected greenhouse area in a week, and the article type record is obtained by identifying the specific type of articles (such as seedlings, tools, fertilizers, etc.) carried by the target object each time it enters or exits and recording; then the historical access mode data containing the daily access frequency, the weekly access frequency of the target object and the article type record carried when entering or exiting is sent to the greenhouse access management system through the data transmission module, providing data support for subsequent determination of the initial disinfection process scheme.

[0062] Step 102: Through the intelligent corridor system, the position coordinate data of the target object in the process of moving between the multi-connected greenhouse areas is obtained to generate the movement trajectory data of the target object, and the movement trajectory data is transmitted to the greenhouse access management system.

[0063] In this step, the intelligent corridor system refers to a system with positioning and data collection functions deployed in the multi-connected greenhouse area along the moving path of the target object, including multiple positioning sites and a data transmission module, for obtaining the position coordinate data of the target object moving between the multi-connected greenhouse areas, and then generating the movement trajectory data, which is the core system for accurately tracking the movement of the target object. The position coordinate data refers to the specific spatial position data (such as X, Y coordinates) collected at the positioning sites of the intelligent corridor system when the target object moves between the multi-connected greenhouse areas, which is obtained based on signal collection and analysis of the positioning sites, used to generate the movement trajectory data and reflect the real-time position of the target object. The movement trajectory data refers to a data set formed by sequentially connecting the position coordinate data in the order of time during the movement of the target object, which is obtained based on the position coordinate data collected by the intelligent corridor system, reflects the moving path of the target object between the multi-connected greenhouse areas, and is used to determine the dominant direction of the movement of the target object and the target greenhouse area that the target object plans to enter.

[0064] Step 103: According to the movement trajectory data, the dominant direction of the movement of the target object is determined, the layout information of the multi-connected greenhouse area pre-stored in the greenhouse access management system is combined to determine the target greenhouse area that the target object plans to enter, and the initial disinfection process scheme is determined according to the historical access mode data.

[0065] In this step, the moving dominant direction refers to the dominant direction of movement of the target object when moving between multiple connected areas of the greenhouse, which is obtained based on statistical analysis of the direction parameters of each adjacent position coordinate group in the movement trajectory data (such as the direction with the highest frequency), combined with interval distance to determine continuity, reflecting the movement trend of the target object, and used to match the candidate greenhouse area. The layout information of the multiple connected areas of the greenhouse refers to the information pre-stored in the greenhouse access management system, reflecting the spatial structure of the multiple connected areas of the greenhouse, including the boundary coordinates of each greenhouse area, the connection position coordinates of each greenhouse area and the intelligent corridor, the preset entering distance from each connection position coordinate to the corresponding greenhouse area, etc., used to match the candidate greenhouse area and determine the target greenhouse area. The target greenhouse area refers to the specific greenhouse area that the target object plans to enter, which is matched based on the moving dominant direction determined from the movement trajectory data and the layout information of the multiple connected areas of the greenhouse, reflecting the movement target of the target object, and is the core reference area for subsequent judgment of whether to allow entry.

[0066] Step 104: Determine an initial disinfection process scheme based on the historical access mode data.

[0067] In this step, the initial disinfection process scheme refers to a preliminary process scheme developed for the target object to disinfect the target object and the carried articles, which is developed based on the historical access mode data and includes disinfection intensity, disinfection method, disinfection duration, etc., used to guide the disinfection equipment to perform disinfection operations.

[0068] Step 105: Execute the initial disinfection process scheme to obtain the disinfection result of the target object, and determine whether to allow the target object to enter the target greenhouse area or leave the greenhouse area where the target object is located, in combination with the target greenhouse area.

[0069] In this step, the disinfection result refers to the result obtained by integrating the stage disinfection data (surface microbial quantity, drug adhesion degree) collected during the disinfection process after the initial disinfection process scheme is executed, including microbial residual amount, disinfection coverage rate, and article surface treatment compliance rate, reflecting the effect of disinfection operation, and used to determine whether to allow the target object to enter the target greenhouse area or leave the greenhouse area where the target object is located.

[0070] The embodiment of the application provides a basis for subsequent dynamic initial disinfection process scheme by collecting historical access mode data, avoids the problem of fixed disinfection strategy of the existing scheme, obtains position coordinate data of the target object by means of the intelligent corridor system and generates movement trajectory data, solves the pain point of discontinuous trajectory of the existing scheme, lays a foundation for accurately determining the movement dominant direction and the target greenhouse area, determines the target greenhouse area based on the movement trajectory data and the layout information, determines the initial disinfection process scheme in combination with the historical data, then obtains the disinfection result by executing the scheme and judges the access permission, realizes real-time sensing of the activity state of the target object and accurate prediction of the behavior intention, guarantees ecological isolation and biological safety of each independent greenhouse unit, meets the flexible and changeable access demand in actual production, balances accurate disinfection and efficient passing, improves operation efficiency and reduces resource waste.

[0071] The embodiment provided in the application provides a step 102, position coordinate data of a target object in the process of moving between multiple connected areas of a greenhouse is obtained by an intelligent corridor system to generate movement trajectory data of the corresponding target object, and the movement trajectory data is transmitted to a greenhouse access management system, and the step specifically includes the following steps:

[0072] Step 201: Obtain the positioning signal of the target object entering the intelligent corridor and moving between multiple connected areas of a greenhouse by the intelligent corridor system, and the positioning signal carries the identification information segment of the corresponding target object.

[0073] In this step, the positioning signal refers to a signal (such as a radio frequency signal) related to the position of the target object captured by the positioning module in the intelligent corridor system, which is used to carry the identification information segment of the corresponding target object, is obtained based on the position-related signal emitted by the target object when entering the intelligent corridor and moving between multiple connected areas of a greenhouse, and is the core input signal for determining the position coordinate data subsequently. The identification information segment refers to part of the unique identification information of the target object (such as the last 8 bits of the unique code or the feature recognition code segment), which is used to preliminarily screen the position coordinate data of the same target object, is obtained based on the identification carrier (such as a built-in chip work card or a device label) carried by the target object together with the positioning signal, and is the preliminary basis for distinguishing the trajectory data of different target objects.

[0074] In the embodiments of the present application, a plurality of positioning modules (such as radio frequency positioning modules) are arranged along the target object moving path in the intelligent corridor system. When the target object enters the intelligent corridor and moves between the multiple connected areas of the greenhouse, these positioning modules will capture the positioning signals emitted by the target object in real time. The positioning signals carry the identification information fragments of the corresponding target object, which are part of the unique identification information of the target object (such as specific fragments of the unique code), used to preliminarily distinguish different target objects. The acquisition of the positioning signals is completed by controlling the intelligent corridor system, providing the original signal source for subsequent determination of the position coordinate data.

[0075] Step 202: determining the position coordinate data of the target object at the corresponding corridor node according to the signal transmission condition of the positioning signal, the corridor node being a positioning site arranged along the target object moving path in the intelligent corridor.

[0076] In this step, the signal transmission condition specifies the characteristics of the positioning signal in the transmission process, including the time of the signal reaching the corridor node, the signal strength, whether the signal is stable, etc., used to judge whether the positioning signal is valid and which corridor node it corresponds to. The real-time detection result of the positioning signal by the signal receiving module of the intelligent corridor system is the key reference for determining the position coordinate data. The corridor node refers to the positioning site arranged along the target object moving path in the intelligent corridor, used to collect the positioning signal of the target object and correspondingly generate the position coordinate data, based on the common moving route planning of the target object in the multiple connected areas of the greenhouse, and is the physical carrier for obtaining the position coordinate data. The position coordinate data refers to the spatial position information (such as the X-axis and Y-axis coordinate values of the two-dimensional plane) of the target object at a specific corridor node, used to constitute the basic unit of the moving track of the target object, based on the matching of the preset fixed coordinates of the corresponding corridor node according to the signal transmission condition, and is the original data for generating the track point sequence. The target object moving path refers to the route that the target object may pass through when moving between the multiple connected areas of the greenhouse, used to guide the layout position of the corridor node, based on the historical moving record of the target object and the channel layout (such as the connecting corridor and shared channel) of the multiple connected areas of the greenhouse, and is the premise for ensuring that the corridor node can comprehensively collect the positioning signal.

[0077] In the embodiments of the present application, the intelligent corridor system pre-stores the fixed position coordinates (such as X and Y axis coordinate values) of each corridor node (i.e. the positioning site arranged along the target object moving path in the intelligent corridor). After obtaining the positioning signal, the control system analyzes the signal transmission of the positioning signal, including the time of the signal reaching each corridor node, the signal strength and the signal stability. If the positioning signal strength received by a certain corridor node reaches the preset effective threshold (i.e. the signal transmission meets the reliable collection condition), the system determines the pre-stored fixed position coordinates of the corridor node as the position coordinate data of the target object at the corridor node, completes the acquisition of the position coordinate data, and the data will be used as the basic unit for generating the trajectory.

[0078] Step 203: associating the position coordinate data of the same target object at each corridor node in the corresponding time sequence to form a plurality of trajectory point sequences, splicing all the trajectory point sequences to form preliminary moving trajectory data.

[0079] In this step, the time sequence refers to the time arrangement order of the intelligent corridor system collecting each position coordinate data, which is used to associate the position coordinate data of the same target object in the moving time sequence, and is obtained based on the time stamp of collecting each position coordinate data, which is the core logical basis for forming the trajectory point sequence. The trajectory point sequence refers to the position coordinate data set of the same target object in the continuous time period, which is associated in the time sequence, and is used to splice to form the preliminary moving trajectory data, and is obtained based on the position coordinate data of the same target object in the time sequence, which is the basic unit reflecting the local moving path of the target object. The preliminary moving trajectory data refers to the trajectory data formed by splicing the plurality of trajectory point sequences of the same target object in the time sequence, which is not bound with the complete identification information, and is used for subsequent association with the identification information of the target object, and is obtained based on the time connection and coordinate splicing of the plurality of trajectory point sequences, which is the intermediate form of generating the final moving trajectory data.

[0080] In the embodiments of the present application, the control intelligent corridor system filters all the position coordinate data belonging to the same target object (ensuring that only the same target object is processed) through the identification information fragment of the target object carried in the positioning signal; then, the time stamp (such as the year, month, day, hour, minute and second of collection) of collecting each position coordinate data is extracted, and these position coordinate data are associated in the time sequence (i.e. the order of collecting the coordinate data) to form a plurality of trajectory point sequences (each trajectory point sequence is the position coordinate set of the same target object in the continuous time period); then, the system splices the trajectory point sequences in the time sequence (such as seamlessly connecting the end coordinate of the previous sequence with the start coordinate of the next sequence) to form the preliminary moving trajectory data which can preliminarily reflect the moving path of the target object, and the preliminary trajectory data provides the basis for subsequent association with the identification information.

[0081] Step 204: associate the preliminary movement trajectory data with the identification information of the corresponding target object, to obtain the movement trajectory data of the corresponding target object, and the identification information is used for the greenhouse shed access management system to identify the target object corresponding to the movement trajectory data.

[0082] In this step, the identification information of the target object refers to complete information (such as the worker's ID + name, the number + model of the work equipment) used to uniquely identify the target object, which is used to bind the movement trajectory data with the specific target object. Based on the matching and integration of the identification information fragment in the positioning signal and the complete identification information pre-stored in the greenhouse shed access management system, it is the key basis for the greenhouse shed access management system to identify the target of the trajectory data.

[0083] In the embodiment of the present application, the greenhouse shed access management system pre-stores the complete identification information of each target object of the target object (such as the worker's ID, the exclusive number of the equipment, etc., which can be matched with the identification information fragment in the positioning signal); control the system to match the preliminary movement trajectory data with the identification information fragment in the positioning signal, find the complete identification information of the target object corresponding to the fragment; then, the preliminary movement trajectory data is bound and associated with the complete identification information of the target object, to obtain the movement trajectory data of the corresponding target object; wherein the identification information of the target object is used for the greenhouse shed access management system to accurately identify the specific target object corresponding to the trajectory data after receiving the movement trajectory data, to avoid confusion of the trajectory data of different target objects, and to ensure the unique correspondence between the trajectory and the target.

[0084] The embodiment of the present application realizes continuous collection of positioning signals by arranging corridor nodes along the moving path of the target object in the intelligent corridor, avoiding signal coverage blind area; determines the position coordinate data of the corresponding corridor node by analyzing the transmission of the positioning signal, ensuring the accuracy of the coordinate data; and obtains the movement trajectory data of the corresponding target object through multiple steps, solving the problems of discontinuous trajectory and confusion of different target trajectories in the existing scheme, providing continuous and accurate trajectory data support, reducing the risk of target intention misjudgment caused by inaccurate trajectory data, and improving the reliability and accuracy of target object movement tracking in the greenhouse shed multi-phase connected area.

[0085] The present application provides a specific embodiment, step 103, according to the movement trajectory data, determine the moving direction of the target object, combine the pre-stored layout information of the greenhouse shed multi-phase connected area in the greenhouse shed access management system, determine the target greenhouse shed area that the target object plans to enter, which specifically includes the following steps:

[0086] Step 301: extract a plurality of position coordinates of the target object and the recording time corresponding to each position coordinate from the movement trajectory data.

[0087] In this step, the position coordinates refer to the spatial position information (usually represented by X-axis and Y-axis values in a two-dimensional plane) recorded by the intelligent corridor at the corridor nodes when the target object moves in the multi-connected area of the greenhouse, which is used to reflect the real-time spatial position of the target object and is the basic data unit for calculating the direction parameter and the interval distance. The recording time corresponding to each position coordinate refers to the specific time (such as year-month-day hour: minute: second) when each position coordinate is collected by the intelligent corridor system, which is used to determine the time sequence relationship of the position coordinates and is obtained based on the timestamp generated synchronously when the intelligent corridor system collects the position coordinates, and is the core basis for dividing adjacent position coordinate groups and judging the moving order.

[0088] In the embodiments of the present application, the control greenhouse access management system calls the moving trajectory data of the corresponding target object, which includes all position coordinates of the target object during movement in the multi-connected area of the greenhouse and the recording time of each coordinate collection; the system extracts the multiple position coordinates (such as the X-axis and Y-axis coordinates corresponding to each corridor node) of the target object one by one from the moving trajectory data through the data analysis module, and extracts the corresponding recording time (such as the collection timestamp to the second) at the time of each position coordinate collection, forming a one-to-one correspondence between the position coordinates and the recording time, and providing the basic data with time sequence for subsequent calculation of the direction parameter and the interval distance.

[0089] Step 302: According to the order of each recording time, the direction parameter and the interval distance of each adjacent position coordinate group are calculated, and the moving dominant direction of the target object is determined according to the direction parameter and the interval distance of each adjacent position coordinate group.

[0090] In this step, the adjacent position coordinate group refers to a set composed of two adjacent position coordinates after sorting according to the recording time corresponding to each position coordinate, which is used to calculate the direction and distance of the target object movement and is obtained based on the time sequence sorting of the position coordinates, and is the basic calculation unit for analyzing the moving dominant direction. The direction parameter refers to the moving direction of the target object corresponding to the adjacent position coordinate group (such as horizontal left, vertical up, diagonal right down, etc.), which is used to reflect the moving trend of the target object and is obtained based on the positive and negative judgment of the horizontal coordinate difference and the vertical coordinate difference in the adjacent position coordinate group, and is the key parameter for determining the moving dominant direction. The interval distance refers to the spatial straight line distance between the two position coordinates in the adjacent position coordinate group, which is used to reflect the moving span of the target object between the two adjacent collection points and is calculated based on the square root of the sum of the square of the horizontal difference and the square of the vertical difference of the adjacent position coordinates, and is used to assist in excluding abnormal moving data and judging the approaching state.

[0091] In this embodiment, the greenhouse access management system sorts the extracted location coordinates according to the chronological order of their corresponding recording times. Adjacent location coordinates are grouped together to form multiple adjacent location coordinate groups. Then, for each adjacent location coordinate group, the interval distance is calculated: the sum of the square of the horizontal coordinate difference between the preceding and following location coordinates and the square of the vertical coordinate difference, followed by taking the square root of this sum, yields the interval distance between adjacent location coordinate groups. Simultaneously, the direction parameter is determined: based on the horizontal coordinate difference (the difference between the X values ​​of the following coordinates and the preceding coordinates). The system determines the direction of movement of the adjacent coordinate group by comparing the X-value and the vertical coordinate difference (the difference between the Y-values ​​of the previous and subsequent Y-values). For example, if the X-value increases and the Y-value remains unchanged, the movement is horizontal to the right; if the X-value remains unchanged and the Y-value increases, the movement is vertical upward. This direction parameter is then used to determine the direction parameter of the adjacent coordinate group. Subsequently, the system counts the direction parameters of all adjacent coordinate groups and uses the direction parameter with the highest frequency as the initial dominant direction. Then, it excludes the direction parameters of abnormal adjacent coordinate groups with an interval distance much greater than the average interval distance (e.g., more than 3 times the average interval distance). Finally, the dominant direction of movement of the target object is determined.

[0092] Step 303: Match candidate greenhouse areas that are consistent with the dominant direction of movement from the layout information of the multi-connected areas of the greenhouse pre-stored in the greenhouse access management system. The layout information includes the boundary coordinates of each greenhouse area, the connection position coordinates between each greenhouse area and the intelligent corridor, and the preset entry distance from each connection position coordinate to the corresponding greenhouse area.

[0093] In this step, the candidate greenhouse area refers to the greenhouse area aligned with the dominant direction of movement of the target object. It is used to initially screen the greenhouse range the target object might enter. This is obtained by matching the dominant direction of movement with the connection coordinates in the layout information of multiple connected greenhouse areas, and serves as an intermediate screening result for determining the target greenhouse area. The boundary coordinates of the greenhouse area refer to the coordinate points used to define the spatial range of a single greenhouse area (such as the coordinates of the four corners of the greenhouse). These are used to clarify the spatial boundaries of the greenhouse and are measured based on the actual construction layout of multiple connected greenhouse areas, serving as the spatial basis for distinguishing different greenhouse areas. The connection coordinates refer to the spatial coordinates of the connection point between each greenhouse area and the intelligent corridor (i.e., the greenhouse entrance). These reflect the connection position between the greenhouse and the corridor and are measured based on the actual connection position between the greenhouse entrance and the corridor. These are key coordinates for matching the dominant direction of movement and calculating straight-line distances. The preset entry distance refers to the standard straight-line distance from the connection coordinates of the greenhouse area to the designated work area or safety area within that greenhouse. This is used to determine the proximity of the target object to the greenhouse entry conditions and is measured based on the internal layout planning of the greenhouse. It is the core reference value for screening multiple candidate areas.

[0094] In the embodiments of the present application, the control system of greenhouse access management system retrieves data from the pre-stored layout information of the greenhouse multi-connected area, which includes the boundary coordinates of each greenhouse area, the connection position coordinates of each greenhouse area and intelligent corridor, and the preset entering distance from each connection position coordinate to the corresponding greenhouse area. The system moving direction is matched with the connection position coordinates of each greenhouse area. If the connection position coordinates of a certain greenhouse area are within the preset angle range based on the current moving direction of the target object (for example, if the moving direction is horizontal right, the connection position coordinates are within the range of ±15° to the right), the greenhouse area is marked as a candidate greenhouse area consistent with the moving direction.

[0095] Step 304: Calculate the straight-line distance between the end position coordinates in the moving trajectory data and the connection position coordinates of each candidate greenhouse area, and select the candidate greenhouse area in which the target object is in the approaching state as the target greenhouse area that the target object plans to enter, by combining the interval distance of the last adjacent position coordinate group. If there are multiple candidate greenhouse areas in which the target object is in the approaching state, the candidate greenhouse area with the minimum difference between the straight-line distance and the corresponding preset entering distance is determined as the target greenhouse area.

[0096] In this step, the end position coordinate refers to the last position coordinate (i.e., the latest collected position coordinate) in the target object movement trajectory data, which is used to reflect the current latest position of the target object, is extracted based on the end data of the movement trajectory data, and is the reference coordinate for calculating the straight-line distance of the connection position of the candidate region. The straight-line distance refers to the spatial straight-line distance between the end position coordinate of the target object and the connection position coordinate of the candidate greenhouse region, which is used to judge the spatial distance between the target object and the candidate region, is calculated based on the horizontal difference and vertical difference of the end position coordinate and the connection position coordinate, and is the core indicator for judging the approaching state. The last adjacent position coordinate group refers to the last group of adjacent position coordinates (i.e., the coordinates of the latest two collection points) in the target object movement trajectory data sorted by recording time, which is used to reflect the latest movement span of the target object, is extracted based on the time sequence sorting of the position coordinates, and is an auxiliary reference unit for judging the approaching state. The interval distance of the last adjacent position coordinate group refers to the straight-line distance between the two coordinates in the last adjacent position coordinate group, which is used to reflect the latest movement distance of the target object, is calculated based on the horizontal difference and vertical difference of the last adjacent position coordinate, and is a reference threshold for judging whether the target object approaches the candidate region. The approaching state refers to the straight-line distance between the end position coordinate of the target object and the connection position coordinate of the candidate greenhouse region, which is within a reasonable range that can determine its movement to the candidate region (such as the straight-line distance being less than 2 times the last adjacent interval distance), which is used to select the candidate region that the target object is actually likely to enter, and is obtained based on the comparison of the straight-line distance and the last adjacent interval distance, which is a key judgment condition for determining the target greenhouse region.

[0097] The embodiment of the present application extracts position coordinates with time sequence from movement trajectory data to ensure the time sequence of direction and distance calculation, and then excludes abnormal data through direction parameter statistics of adjacent coordinate groups to avoid misjudgment of the dominant direction caused by deviation of a single coordinate point. Then, the target range is narrowed by matching the connection position coordinate in the layout information with the candidate region. Finally, the target region is accurately locked through distance comparison of the end coordinate and the candidate region and preset entering distance difference screening. The whole process solves the core problems of existing schemes, such as ambiguous direction judgment and destination misjudgment, provides accurate target basis for formulating disinfection schemes and judging access permissions in combination with target regions, effectively guarantees the accuracy of access management in multiple connected regions of greenhouse, reduces errors caused by misjudgment of target regions, and improves overall management efficiency.

[0098] The present application provides a specific embodiment, step 104, determining an initial disinfection process scheme according to the historical access mode data, specifically including the following steps:

[0099] Step 401: According to the historical access mode data, the weekly average access frequency of the target object in a preset period is calculated, and the weekly average access frequency is compared with a preset frequency threshold range to determine the corresponding disinfection intensity level.

[0100] In this step, the preset period refers to a pre-set time range (such as 30 days, 60 days) for counting the access frequency of the target object, which is used to calculate the weekly average access frequency to reflect the long-term access rule, and is obtained based on the statistical demand of historical data and the greenhouse management period setting, and is the time basis for calculating the weekly average access frequency. The weekly average access frequency refers to the number of times the target object enters or leaves the greenhouse area or the area adjacent to the greenhouse in a week in the preset period, which is used to reflect the long-term access frequency of the target object, and is calculated based on the total access frequency in the preset period divided by the number of weeks in the period, and is the core index for determining the disinfection intensity level. The preset frequency threshold range refers to a plurality of weekly average access frequency intervals (such as 1-3 times / week, 4-6 times / week, etc.) set in advance, each interval corresponds to a disinfection intensity level, which is used to convert the weekly average access frequency into specific disinfection intensity standard, and is obtained based on the greenhouse biological safety control demand and historical data distribution setting, and is the basis for dividing the disinfection intensity level. The disinfection intensity level refers to the disinfection intensity level determined according to the access frequency of the target object (such as low, medium, high), which is used to match the corresponding basic disinfection parameters, and is determined based on the comparison result of the weekly average access frequency and the preset frequency threshold range, and is the quantitative index of the disinfection scheme intensity.

[0101] In the embodiment of the application, the control greenhouse access management system first extracts all access records of the target object in a preset period (such as 30 days) from the historical access mode data, counts the total access frequency in the period, and then divides the total access frequency by the number of weeks in the preset period (such as 30 days corresponding to 4 weeks and 2 days, which is calculated as 4 weeks) to obtain the weekly average access frequency of the target object in the preset period. The system has a plurality of preset frequency threshold ranges (such as 1-3 times per week, 4-6 times per week, 7 times per week and above), each range corresponds to a disinfection intensity level (such as low, medium, high), and the calculated weekly average access frequency is compared with these threshold ranges, and the disinfection intensity level corresponding to the range into which it falls is determined, which provides the intensity basis for determining the basic disinfection parameters subsequently.

[0102] Step 402: According to the disinfection intensity level, the basic disinfection parameters are determined, including disinfection time, disinfection agent concentration and disinfection range.

[0103] In this step, the basic disinfection parameter refers to the disinfection core index set determined according to the disinfection intensity level, including disinfection time, disinfection agent concentration and disinfection range, which is used to standardize the basic standard of disinfection operation, and is obtained based on the matching of the disinfection intensity level and the pre-stored parameter rule, and is the basic framework for subsequent refinement of disinfection mode. The disinfection time refers to the length of time required to complete one disinfection operation (such as 5 minutes, 10 minutes), which is used to control the duration of disinfection operation, and is determined based on the disinfection intensity level, and is a time index reflecting disinfection sufficiency in the basic disinfection parameter. The disinfection agent concentration refers to the proportion of effective components of the agent used in the disinfection process (such as 0.1%, 0.3%), which is used to control the efficacy of disinfection agent, and is determined based on the disinfection intensity level, and is a chemical index reflecting disinfection effect in the basic disinfection parameter. The disinfection range refers to the area covered by the disinfection operation (such as hands, whole body, surface of articles, etc.), which is used to define the spatial boundary of disinfection operation, and is determined based on the disinfection intensity level, and is a spatial index reflecting the comprehensiveness of disinfection in the basic disinfection parameter.

[0104] In the embodiment of the present application, according to the determined disinfection intensity level, the pre-stored intensity-parameter corresponding rule in the greenhouse shed access management system is called: if it is a low disinfection intensity level, the disinfection time in the basic disinfection parameter is set to a shorter time (such as 5 minutes), the disinfection agent concentration is set to a lower concentration (such as 0.1%), and the disinfection range is limited to the hands of the target object and the surface of the carried articles; if it is a medium disinfection intensity level, the disinfection time is set to a medium time (such as 10 minutes), the disinfection agent concentration is set to a medium concentration (such as 0.3%), and the disinfection range is extended to the whole body of the target object and all carried articles; if it is a high disinfection intensity level, the disinfection time is set to a longer time (such as 15 minutes), the disinfection agent concentration is set to a higher concentration (such as 0.5%), and the disinfection range covers the whole area of the target object and the carried articles, so as to determine the basic disinfection parameter including disinfection time, disinfection agent concentration and disinfection range, and provide a basic standard for subsequent matching of disinfection mode.

[0105] Step 403: Grouping each type of article in the article type record according to the article material category to obtain a plurality of article groups, and counting the occurrence frequency and the average number of single carrying of each article group. The article material of the article group with the highest occurrence frequency is marked as the main material category, and the article groups other than the main material category are marked as the secondary material category.

[0106] In this step, the article material category refers to a category divided according to the article manufacturing material (such as metal, plastic, cotton, etc.), which is used to group the carrying articles to match the targeted disinfection mode, is predefined based on the material properties of common articles, and is the classification basis for article grouping. The article group refers to a set of articles of the same material category in the article type record, which is used to count the carrying characteristics of the same type of articles, is classified based on the article material category, and is the basic unit for analyzing the article carrying rule. The occurrence frequency refers to the total number of occurrences of each article group in the historical access records of the target object, which is used to reflect the carrying frequency of the article group, is counted based on the number of occurrences of the article group in all access records, and is the core basis for distinguishing the main / secondary material category. The average number of single carrying refers to the average number of each article group when it is carried each time, which is used to adjust the disinfection time, is calculated based on the total carrying number of the article group divided by the occurrence frequency, and is the reference index for dynamic adjustment of the disinfection time. The main material category refers to the article material corresponding to the article group with the highest occurrence frequency, which is used to match a more stringent special disinfection mode, is determined based on the sorting of the occurrence frequency of the article group, and is the material object of the key disinfection. The secondary material category refers to the material of the article group other than the main material category, which is used to match a simplified disinfection mode, is indirectly obtained based on the determination of the main material category, and is the material object of the secondary disinfection.

[0107] In the embodiment of the present application, the predefined article material categories (such as metal, plastic, cotton, glass, etc.) in the greenhouse shed access management system are retrieved, and then the article type records in the historical access mode data are traversed. According to the material properties of various articles, the articles of the same material category are grouped into a group to form multiple article groups. Then, the number of occurrences of each article group in all access records is counted to obtain the occurrence frequency of each article group. At the same time, the average value of the number of each article group when it is carried each time (i.e., the total carrying number of the article group divided by the number of occurrences) is calculated to obtain the average number of single carrying. The article material corresponding to the article group with the highest occurrence frequency is marked as the main material category, and the materials of the remaining article groups are marked as the secondary material category, which provides a material basis for subsequent differentiation of disinfection modes.

[0108] Step 404: According to the basic disinfection parameters, the article group marked as the main material category is matched with the corresponding special disinfection mode, and the article group marked as the secondary material category is matched with the corresponding simplified disinfection mode according to the occurrence frequency of each article group. According to the comparison result of the average number of single carrying of each article group and the preset number threshold, the disinfection time of the corresponding disinfection mode is extended or shortened.

[0109] In this step, the special disinfection method refers to the special disinfection method designed for the main material category object group and meeting the material characteristics (such as alcohol wiping + ultraviolet irradiation for metal), which is used to ensure the disinfection effect of high-frequency carrying objects, and is obtained by matching the basic disinfection parameters and the characteristics of the main material category, and is the core disinfection means of the main objects. The simplified disinfection method refers to the relatively simple disinfection method designed for the secondary material category object group (such as water wiping for glass), which is used to improve efficiency while ensuring basic disinfection effect, and is obtained by matching the basic disinfection parameters and the occurrence frequency of the secondary material category, and is the auxiliary disinfection means of the secondary objects. The preset quantity threshold refers to the critical value for judging the number of objects carried, which is used to adjust the disinfection time, and is obtained by balancing the efficiency and effect of object disinfection, and is the judgment standard for disinfection time adjustment. The corresponding disinfection method refers to the special or simplified disinfection method matched with a specific object group (main or secondary material category), which is used to clarify the specific disinfection operation of different objects, and is determined based on the material category and occurrence frequency of the object group, and is the specific execution scheme of object disinfection.

[0110] In the embodiment of the application, according to the basic disinfection parameters, the special disinfection method is matched for the object group of the main material category (such as the combination of alcohol wiping + ultraviolet irradiation for metal objects, and the special disinfection agent spraying method for plastic objects), to ensure the disinfection effect of high-frequency appearing objects of this category; for the object group of the secondary material category, the simplified disinfection method is matched according to the occurrence frequency (such as water wiping + air drying for glass objects with low occurrence frequency); at the same time, the system has a preset quantity threshold (such as 5 pieces), if the average number of single carrying of an object group is greater than the threshold, the disinfection time of the corresponding disinfection method is extended by a preset proportion (such as 20%), if it is less than or equal to the threshold, it is shortened by a preset proportion (such as 10%), so as to adjust the disinfection time, so that the disinfection method is more suitable for the actual carrying situation.

[0111] Step 405: According to the use label of each type of object, it is judged whether there is sensitive object, if there is sensitive object, the specific processing method corresponding to the use label is added in the disinfection method corresponding to the sensitive object, to form the initial disinfection process scheme.

[0112] In this step, the use label of various types of articles: the label marked on the article indicating its function or use (such as seedlings, precision instruments), used to judge whether the article is a sensitive article, pre-marked based on the actual use of the article, and is the basis for identifying sensitive articles. Sensitive articles refer to articles that have special requirements for disinfection methods (such as fear of high-concentration chemicals and fear of liquid), which are used to trigger specific processing methods, and are determined based on the use label of various types of articles, which are articles that require special disinfection processing. Specific processing method refers to a disinfection method designed for the use label of sensitive articles that meets their special requirements (such as low-concentration atomized spraying for seedlings), which is used to ensure that sensitive articles remain functional after disinfection, and is obtained by matching the use label of sensitive articles with pre-stored processing rules, which is a special disinfection supplement for sensitive articles.

[0113] In the embodiments of the present application, it is checked whether various types of articles are provided with use labels (such as seedling, pesticide, precision instrument, etc.), and it is determined whether there are sensitive articles (i.e. articles that have special requirements for disinfection methods, such as seedlings that fear high-concentration chemicals and precision instruments that fear liquid immersion) according to the labels; if there are sensitive articles, a specific processing method matching the use label is added in the disinfection method corresponding to the article (such as low-concentration chemicals + atomized spraying for seedlings, and dry fog disinfection + anti-static wiping for precision instruments); the special disinfection method for the main material category, the simplified disinfection method (including time adjustment) for the secondary material category, and the specific processing method for sensitive articles are integrated to form an initial disinfection process scheme for the target object and the carried articles, providing specific execution basis for subsequent disinfection operations.

[0114] The embodiments of the present application avoid redundancy or deficiency caused by fixed intensity by calculating weekly data based on historical entry and exit frequency and matching disinfection intensity; group articles by material and distinguish between primary and secondary categories to achieve rational allocation of disinfection resources; adjust the time based on the number of carried articles and add specific processing for sensitive articles to ensure the balance between disinfection effect and article protection. The entire process solves the problem of rigid disinfection strategy in existing solutions, making the initial disinfection process scheme not only meet the greenhouse biological safety control requirements, but also adapt to the actual entry and exit rules of the target object and the characteristics of the carried articles, ensuring the disinfection effect while improving the efficiency of passing through and reducing unnecessary resource consumption.

[0115] The present application provides a specific embodiment as shown in Figure 2 As shown in FIG. 1, step 105, the initial disinfection process scheme is executed to obtain the disinfection result of the target object, and in combination with the target greenhouse area, it is determined whether the target object is allowed to enter the target greenhouse area or leave the greenhouse area where the target object is located, which specifically includes the following steps:

[0116] Step 501: Send a start instruction to the disinfection equipment in the intelligent corridor through the greenhouse access management system, to obtain a plurality of sets of stage disinfection data when the disinfection equipment executes the initial disinfection process scheme, the stage disinfection data including surface microorganism quantity and medicament adhesion degree data of the target object and various objects.

[0117] In this step, the start instruction refers to the control instruction generated by the greenhouse access management system based on the initial disinfection process scheme for triggering the operation of the disinfection equipment in the intelligent corridor, including the execution steps (such as disinfection time, disinfection medicament concentration) of the initial disinfection process scheme, for ensuring that the disinfection equipment starts the disinfection operation according to the preset scheme, which is generated based on the specific parameters of the initial disinfection process scheme. The stage disinfection data refers to a set of stage data related to the disinfection effect collected in real time during the execution of the initial disinfection process scheme by the disinfection equipment, including surface microorganism quantity and medicament adhesion degree data of the target object and various objects, reflecting the disinfection progress at different stages in the disinfection process, for subsequent integration to form complete disinfection results, which is collected in real time based on the microorganism sensor and medicament concentration sensor deployed on the disinfection equipment. The surface microorganism quantity refers to the number of microorganisms (such as bacteria and fungi) on the surface of the target object (such as hands and clothes) and various objects carried, which is collected by the sensor, reflecting the change of microorganism residues before, during and after disinfection, for calculating the microorganism residue, which is obtained based on the data collected by the microorganism sensor at different positions at fixed intervals during the disinfection process. The medicament adhesion degree data refers to the adhesion concentration of the disinfection medicament on the surface of the target object and various objects, which is collected by the sensor, reflecting the coverage of the disinfection medicament on the surface, for assisting in judging whether the disinfection is sufficient and the dryness of the object surface, which is obtained based on the synchronous collection by the medicament concentration sensor during the disinfection process.

[0118] Step 502: After the execution of the initial disinfection process scheme, integrate all the stage disinfection data to form a disinfection result, the disinfection result including microorganism residue, disinfection coverage rate and object surface treatment compliance rate.

[0119] In this step, the disinfection result refers to the comprehensive data reflecting the overall disinfection effect obtained by integrating and calculating all stage disinfection data after the initial disinfection process scheme is completed, including microbial residual amount, disinfection coverage rate and article surface treatment compliance rate, which are used for comparison with access standards or exit standards to determine whether the disinfection is qualified, and are obtained based on the statistics and calculation of stage disinfection data. The microbial residual amount refers to the final residual value obtained by integrating the number of surface microorganisms in the stage disinfection data (usually the average value of multiple data collected after disinfection), which reflects the remaining microorganisms on the target object and the surface of the article after disinfection, and is used for comparison with the allowable microbial residual threshold of access or exit, and is obtained based on the statistics and calculation of the number of surface microorganisms in the stage disinfection data. The disinfection coverage rate refers to the ratio of the actual covered area in the disinfection process to the disinfection range area set in the initial disinfection process scheme, which reflects the spatial coverage sufficiency of disinfection operation, and is used for comparison with the required disinfection area ratio of access, and is obtained based on the statistics and calculation of the running track data of the disinfection equipment and the area of the set disinfection range. The article surface treatment compliance rate refers to the ratio of the number of articles with surface microbial quantity below the preset compliance value to the total number of articles carried by the target object, which reflects the disinfection compliance degree of the carried articles, and is used for comparison with the specific article treatment requirement or the cleanliness requirement of the carried articles, and is obtained based on the statistics of the compliance of the number of surface microorganisms of the articles in the stage disinfection data.

[0120] Step 503: If the target object is planned to enter the target greenhouse area, the disinfection result is compared with the access standard corresponding to the target greenhouse area in the layout information of the multi-connected greenhouse area, and if the target object is to leave the greenhouse area where it is located, the disinfection result is compared with the exit standard corresponding to the greenhouse area where the target object is located in the layout information of the multi-connected greenhouse area, to obtain a disinfection qualification judgment result, so as to determine whether the target object is allowed to enter the target greenhouse area or leave the greenhouse area where the target object is located.

[0121] In this step, the access standard refers to the disinfection qualified access condition set for the target greenhouse area in the pre-stored layout information of the multi-connected area of the greenhouse, including the access allowed microbial residue threshold, the access required disinfection area proportion, and the specific article processing requirement corresponding to the access prohibited pollutants, for judging whether the disinfection before the target object enters the target greenhouse area is qualified, which is set based on the crop type and the bio-safety level of the target greenhouse area. The leaving standard refers to the disinfection qualified leaving condition set for the greenhouse area where the target object is located in the pre-stored layout information of the multi-connected area of the greenhouse, including the leaving allowed microbial residue threshold, the leaving required dryness requirement, and the leaving carried article cleanliness requirement, for judging whether the disinfection before the target object leaves the greenhouse area is qualified, which is set based on the pollutant control requirement of the greenhouse area where the target object is located. The disinfection qualified judgment result refers to the result generated by comparing the disinfection result with the access standard or the leaving standard, including the disinfection qualified result and the disinfection unqualified result, for determining whether to allow the target object to enter or leave, which is generated based on the comparison result of the disinfection result and the corresponding standard.

[0122] Optionally, in step 503, if the target object is planned to enter the target greenhouse area, the disinfection result is compared with the access standard corresponding to the target greenhouse area in the layout information of the multi-connected area of the greenhouse, and if the target object is to leave the greenhouse area where it is located, the disinfection result is compared with the leaving standard corresponding to the greenhouse area where the target object is located in the layout information of the multi-connected area of the greenhouse, to obtain the disinfection qualified judgment result, for determining whether to allow the target object to enter the target greenhouse area or leave the greenhouse area where the target object is located, specifically including the following steps:

[0123] In step 511, if the target object is planned to enter the target greenhouse area, the access standard corresponding to the target greenhouse area is extracted from the layout information of the multi-connected area of the greenhouse, including the access allowed microbial residue threshold, the access required disinfection area proportion, and the specific article processing requirement corresponding to the access prohibited pollutants.

[0124] In this step, the access allowed microbial residue threshold refers to the maximum microbial residue allowed for the target object and the carrying article to enter the target greenhouse area, reflecting the upper limit of the tolerance of the target greenhouse area to microbial pollution, and is used to determine whether the microbial residue meets the standard, and is set based on the disease resistance of crops in the target greenhouse area. The access required disinfection area proportion refers to the minimum disinfection coverage ratio that the target object must reach before entering the target greenhouse area, reflecting the spatial coverage requirement of disinfection operation, and is used to determine whether the disinfection coverage rate meets the standard, and is set based on the biological safety control level of the target greenhouse area. The access prohibited pollutants refer to specific pollutants (such as insect eggs and specific pathogenic bacteria) that are prohibited to be brought into the target greenhouse area, reflecting the types of pollution that need to be controlled in the area, and are used to develop specific article processing requirements, and are set based on the types of pollutants that crops in the target greenhouse area are susceptible to. The specific article processing requirements refer to the disinfection processing standards set for articles that may carry access prohibited pollutants (such as insect eggs-free seedlings and pathogenic bacteria-free tools), reflecting the special disinfection needs of specific articles, and are used to determine whether the article surface treatment meets the standard, and are set based on the characteristics of access prohibited pollutants and the material of the article.

[0125] Step 512: Compare the disinfection result with the access standard to mark the access disinfection qualified items and the access disinfection unqualified items.

[0126] In this step, the access disinfection qualified item refers to an index item that meets the requirements of the access standard after comparing the disinfection result with the access standard (such as microbial residue being lower than the access allowed microbial residue threshold and disinfection coverage rate reaching the access required disinfection area proportion), reflecting the part that meets the standard in the disinfection process, and is used to finally determine whether the disinfection is qualified, and is obtained based on the comparison of the disinfection result with the access standard. The access disinfection unqualified item refers to an index item that does not meet the requirements of the access standard after comparing the disinfection result with the access standard (such as microbial residue being higher than the access allowed microbial residue threshold and disinfection coverage rate not reaching the access required disinfection area proportion), reflecting the part that does not meet the standard in the disinfection process, and is used to generate a disinfection unqualified result and a prompt, and is obtained based on the comparison of the disinfection result with the access standard.

[0127] Step 513: If the target object is leaving the greenhouse area it is in, extract the leaving standard of the greenhouse area where the target object is in from the layout information of the greenhouse multi-phase connected area, the leaving standard including the leaving allowed microbial residue threshold, the leaving required dryness requirement, and the leaving carrying article cleanliness requirement.

[0128] In this step, the leaving allowable microbial residue threshold refers to the maximum microbial residue allowed for the target object and the carrying article when leaving the greenhouse area set in the leaving standard, reflecting the control requirement for carrying pollutants when leaving, and is used to determine whether the microbial residue meets the standard and is set based on the environmental safety requirements outside the greenhouse area. The leaving necessary dryness requirement refers to the surface dryness required for the target object and the carrying article when leaving the greenhouse area set in the leaving standard (usually indirectly judged by the pesticide adhesion data, and the pesticide adhesion below the preset dryness threshold is considered dry), reflecting the control requirement for the humidity of the article when leaving, and is used to determine whether the surface of the article meets the leaving condition and is set based on the sensitivity of the environment outside the greenhouse area to humidity. The leaving carrying article cleanliness requirement refers to the cleanliness required for the target object and the carrying article when leaving the greenhouse area set in the leaving standard (usually reflected by the article surface treatment compliance rate), reflecting the control requirement for the cleanliness of the carrying article when leaving, and is used to determine whether the article surface treatment compliance rate meets the standard and is set based on the production environment requirements outside the greenhouse area.

[0129] Step 514: Compare the disinfection result with the leaving standard to mark the leaving disinfection qualified items and the leaving disinfection unqualified items.

[0130] In this step, the leaving disinfection qualified item refers to the index item that meets the leaving standard requirement after comparing the disinfection result with the leaving standard (such as the microbial residue being lower than the leaving allowable microbial residue threshold and the article surface dryness meeting the leaving necessary dryness requirement), reflecting the part that meets the standard in the disinfection process, and is used to finally determine whether the disinfection is qualified, and is obtained based on the comparison of the disinfection result with the leaving standard. The leaving disinfection unqualified item refers to the index item that does not meet the leaving standard requirement after comparing the disinfection result with the leaving standard (such as the microbial residue being higher than the leaving allowable microbial residue threshold and the article surface dryness not meeting the leaving necessary dryness requirement), reflecting the part that does not meet the standard in the disinfection process, and is used to generate the disinfection unqualified result and prompt, and is obtained based on the comparison of the disinfection result with the leaving standard.

[0131] Step 515: If there is no access disinfection unqualified item or no leaving disinfection unqualified item, generate a disinfection qualified result, and if there is any unqualified item, generate a disinfection unqualified result with all unqualified items, and take the disinfection qualified result or the disinfection unqualified result as the disinfection qualified judgment result.

[0132] In this step, the disinfection qualified result refers to a result indicating that the disinfection meets the standard, which is generated when there is no access disinfection unqualified item (entering the scene) or no leaving disinfection unqualified item (leaving the scene), and is used to trigger the instruction of allowing entering or leaving, and is generated based on the comparison result of the disinfection result and the corresponding standard. Any unqualified item refers to at least one access disinfection unqualified item in the entering scene or at least one leaving disinfection unqualified item in the leaving scene, reflecting that there is a link that does not meet the standard in the disinfection process, and is used to trigger the disinfection unqualified result, which is determined based on the comparison result of the disinfection result and the corresponding standard. The disinfection unqualified result refers to a result indicating that the disinfection does not meet the standard, which is generated when there is any unqualified item, and is accompanied by specific information of all unqualified items (such as excessive microbial residue and insufficient disinfection coverage), and is used to trigger the instruction and prompt of prohibiting entering or leaving, and is generated based on the comparison result of the disinfection result and the corresponding standard.

[0133] Step 516: determining whether to allow the target object to enter the target greenhouse area or leave the greenhouse area where the target object is located according to the disinfection qualified judgment result.

[0134] Optionally, in step 516, whether to allow the target object to enter the target greenhouse area or leave the greenhouse area where the target object is located is determined according to the disinfection qualified judgment result, and specifically includes the following steps:

[0135] Step 521: if the disinfection qualified judgment result is the disinfection qualified result, an opening instruction is sent to an entrance control device of the target greenhouse area or an opening instruction is sent to an exit control device of the greenhouse area where the target object is located through the greenhouse access management system, so that the target object enters the target greenhouse area or leaves the greenhouse area where the target object is located.

[0136] In this step, the entrance control device refers to a device (such as an electric door and an access control device) deployed at the entrance of the target greenhouse area, which is used to control the opening and closing of the entrance, execute the opening or closing instruction, and realize the switch control based on the instruction sent by the greenhouse access management system, and is an execution component for allowing or prohibiting the target object to enter. The opening instruction refers to a control instruction sent by the greenhouse access management system to the entrance control device or the exit control device when the disinfection is qualified, which is used to open the entrance or exit, contains parameters such as the opening time and permission, and is used to allow the target object to enter or leave, and is generated based on the disinfection qualified result. The exit control device refers to a device (such as an electric door and an access control device) deployed at the exit of the greenhouse area where the target object is located, which is used to control the opening and closing of the exit, execute the opening or closing instruction, and realize the switch control based on the instruction sent by the greenhouse access management system, and is an execution component for allowing or prohibiting the target object to leave.

[0137] Step 522: If the disinfection qualification judgment result is a disinfection unqualified result, send a prohibition instruction to the entrance control device of the target greenhouse area or the exit control device of the greenhouse area where the target object is located through the greenhouse access management system, and display all unqualified items on the display device of the intelligent corridor.

[0138] In this step, the prohibition instruction refers to the control instruction sent by the greenhouse access management system to the entrance control device or the exit control device when disinfection is unqualified, which is used to prohibit the opening of the entrance or exit, contains the reason associated code of prohibition of opening, and is generated based on the disinfection unqualified result. The display device of the intelligent corridor refers to the terminal equipment (such as a liquid crystal display screen) deployed in the intelligent corridor for displaying information, which is used to display the specific content of all unqualified items when disinfection is unqualified, so that the target object or the management personnel can understand the unqualified link and adjust the disinfection operation, and the content display is realized based on the unqualified item information sent by the greenhouse access management system.

[0139] In the embodiments of the present application, first, disinfection starting and phased data collection are realized through step 501: execution parameters (such as disinfection duration of 10 minutes, disinfectant concentration of 0.3%) in an initial disinfection process scheme are extracted, starting instructions containing the parameters are generated, and the starting instructions are sent to disinfection equipment in the intelligent corridor through a data transmission module of the greenhouse shed access management system; after receiving the starting instructions, the disinfection equipment starts disinfection operations (such as spraying disinfectant and turning on ultraviolet lamps) according to the parameters in the instructions, and at the same time, a microorganism sensor on the disinfection equipment collects the number of microorganisms on the hands of the target object, the surface of clothes, and the surface of carried articles (such as seedlings and tools) at an interval of 1 minute, and a disinfectant concentration sensor synchronously collects the adhesion degree data of the disinfectant on these parts, and the data is packaged and transmitted back to the greenhouse shed access management system every time it is collected, forming multiple sets of phased disinfection data. Secondly, disinfection results are integrated through step 502: after the initial disinfection process scheme is executed (such as 10 minutes of disinfection ends), the greenhouse shed access management system receives all the phased disinfection data, and the data is integrated and calculated: the average value of the number of microorganisms on the surface for the last three times is taken as the residual amount of microorganisms, the ratio of the actual covered area of the disinfection equipment to the set disinfection range area is calculated to obtain the disinfection coverage rate, the ratio of the number of articles with a surface microorganism number lower than the standard value to the total number of carried articles is calculated to obtain the article surface treatment compliance rate, and the three indexes are integrated as the disinfection results.Then, the standard comparison and judgment result generation are realized through optional steps 511-516 of step 503: if the target object is to enter the target greenhouse area, first, the access standard of the target greenhouse area is retrieved from the layout information of the multiple connected areas of the greenhouse through step 511, which includes the access allowed microbial residue threshold, the access required disinfection area proportion, and the seedling no-egg treatment requirements corresponding to the access prohibited pollutants (such as insect eggs); then, the disinfection results are compared with the access standard item by item through step 512: if the microbial residue amount ≤ the access allowed microbial residue threshold, it is marked as an access disinfection qualified item, otherwise it is an access disinfection unqualified item; if the disinfection coverage rate ≥ the access required disinfection area proportion, it is marked as an access disinfection qualified item, otherwise it is an access disinfection unqualified item; if the item surface treatment compliance rate meets the seedling no-egg requirement, it is marked as an access disinfection qualified item, otherwise it is an access disinfection unqualified item; if the target object is to leave the area where it is located, the leaving standard of the area is retrieved from the layout information through step 513, including the leaving allowed microbial residue threshold, the leaving required dryness requirement (the pesticide adhesion degree below the dryness threshold is considered to meet the requirement) and the leaving carried article cleanliness requirement; the disinfection results are compared with the leaving standard item by item through step 514: if the microbial residue amount ≤ the leaving allowed microbial residue threshold, it is a leaving disinfection qualified item, otherwise it is a leaving disinfection unqualified item; if the pesticide adhesion degree is below the dryness threshold, it is a leaving disinfection qualified item, otherwise it is a leaving disinfection unqualified item; if the item surface treatment compliance rate ≥ the cleanliness requirement, it is a leaving disinfection qualified item, otherwise it is a leaving disinfection unqualified item; then, it is judged through step 515: if there is no access disinfection unqualified item in the entering scenario or no leaving disinfection unqualified item in the leaving scenario, a disinfection qualified result is generated; if there is any unqualified item, a disinfection unqualified result with all unqualified item specific information is generated, which is used as the disinfection qualified judgment result. Finally, the entry and exit control is realized through optional steps 521-522 of step 516: if the disinfection qualified judgment result is the disinfection qualified result, the greenhouse entry and exit management system sends an opening instruction (the instruction includes the parameter of opening the entrance for 5 minutes) to the entrance control device of the target greenhouse area, or sends an opening instruction to the exit control device of the area, and the entrance or exit control device opens after receiving the instruction, allowing the target object to enter or leave; if the disinfection qualified judgment result is the disinfection unqualified result, the system sends a prohibition instruction (including the unqualified reason associated code) to the entrance or exit control device, and at the same time sends all unqualified item information to the display device of the intelligent corridor, and the display device displays these information in real time (such as microbial residue exceeding the standard, insufficient disinfection coverage rate).

[0140] Assuming the target object is worker A, the target greenhouse area planned to enter is greenhouse B (which plants sensitive seedlings and needs to strictly control egg pollution), the current greenhouse area is greenhouse C, and the initial disinfection process scheme has been determined by the greenhouse access management system as 10 minutes of atomization disinfection + ultraviolet irradiation, with a drug concentration of 0.3%. First, the greenhouse access management system sends a start instruction containing the scheme parameters to the disinfection equipment in the intelligent corridor. After the disinfection equipment starts, it collects the number of microorganisms on the hands, clothes, and 20 seedlings carried by worker A every 1 minute, synchronously collects the drug adhesion degree data on the surface of the seedlings, and transmits 10 sets of stage disinfection data back to the system; After 10 minutes of disinfection, the system integrates the data: take the average of the last 3 surface microorganism counts (such as 50 CFU) as the residual microorganism amount, calculate the disinfection coverage rate by the ratio of the disinfection coverage area to the set range (such as 95%), and calculate the article surface treatment compliance rate by the ratio of the number of seedlings with a surface microorganism count below 30 CFU (19) to the total number of seedlings (95%) to form the disinfection result. Since worker A plans to enter greenhouse B, the system extracts the access standards of greenhouse B from the layout information: the access allowed microorganism residual threshold is 60 CFU, the access required disinfection area ratio is 90%, and the access prohibited pollutants (eggs) correspond to the seedling egg treatment requirement (article surface treatment compliance rate ≥ 90%); Compare the disinfection result with the standard: the residual microorganism amount is 50 CFU ≤ 60 CFU (access disinfection qualified item), the disinfection coverage rate is 95% ≥ 90% (access disinfection qualified item), and the article surface treatment compliance rate is 95% ≥ 90% (access disinfection qualified item), there is no access disinfection unqualified item, and the disinfection qualified result is generated as the disinfection qualified judgment result; The system sends an open instruction (open for 5 minutes) to the entrance control device of greenhouse B, the entrance control device is opened, and worker A enters greenhouse B. If the integrated residual microorganism amount is 70 CFU (higher than the access allowed microorganism residual threshold), it is marked as an access disinfection unqualified item, and a disinfection unqualified result with an excessive microorganism residual amount is generated, the system sends a prohibition instruction to the entrance control device of greenhouse B, and the display device of the intelligent corridor displays the unqualified item of the excessive microorganism residual amount, worker A needs to be disinfected again. CFU refers to Colony-Forming Unit, which refers to the number of viable microorganisms per unit volume (or weight) that can grow and form a single colony under laboratory culture conditions, and is a commonly used unit for measuring the concentration of viable microorganisms in a sample, widely used in the field of microbial detection.

[0141] The embodiments of the present application ensure traceability of the disinfection process through multi-dimensional phased data collection, and avoid deviation of single data judgment; the disinfection results containing three core indicators are generated by integrating data, so as to realize comprehensive evaluation of the disinfection effect; the corresponding access / exit standards are matched according to the entering / leaving scene, the judgment basis is clear, and the standard ambiguity problem is solved; the opening / inhibition instructions are accurately sent based on the judgment result, and the specific problems are displayed through the display device when unqualified, so as to facilitate rapid adjustment of disinfection operation. The whole process not only guarantees the biological safety of the multi-phase connected area of the greenhouse (that is, the pollutants are controlled to be brought in and out through strict standard comparison), but also improves the efficiency of access management (that is, the invalid waiting is reduced through clear judgment and instructions), avoids the wrong control or resource waste caused by ambiguous judgment, and realizes the balance between precise disinfection and efficient passing.
